电感耦合等离子发射光谱仪法测定次氯酸钠中砷和铅的方法研究

Determination of arsenic and lead in sodium hypochlorite by inductively coupled plasma emission spectrometry

次氯酸钠溶液作为消毒、杀菌的水处理剂,需要分析其中的重金属、砷的含量,国家质量监督检验检疫总局发布的标准中分析次氯酸钠中重金属、砷的方法繁琐,本文旨在采用电感耦合等离子发射光谱仪法通过试验确定最佳谱线、标准加入量等准确测定砷、铅的含量。

Sodium hypochlorite solution as a water treatment agent for disinfection and sterilization needs to analyze the contents of heavy metals and arsenic.The standard issued by the General administration of Quality supervision,Inspection and quarantine is complicated.The purpose of this paper is to determine the best spectral line and standard dosage of arsenic and lead accurately by ICP-AES through experiments.
